CONSTRUCTION:
CORE
Our cores are crafted from cold-rolled grain-oriented (CRGO) silicon steel. Automated machinery ensures precise cutting for reduced air gaps, low excitation current, and minimal noise. Each lamination is insulated to guarantee a long, trouble-free core life. Utilizing a 45° stepping technique, the laminations are arranged to efficiently reduce no-load current.
machines thereby ensuring reduced air gap, low exciting current and low noise. Each lamination is insulated from each other to ensure a long trouble-free lifetime of the core. Using 45° stepping all leaning lamination way to laminate. So the no-load current are reduced efficiently.
WINDINGS
Our LV windings are made with high-quality foil conductor or copper wire, ensuring balanced ampere-turn and lower additional loss. This enhances anti-short circuit capability. Optimized oil drawings for heat dispersion increase the surface area for heat dissipation, thereby reducing temperature and enhancing overload capacity.
temperature is reduced and the ability of over-load is improved.
The HV winding is masterfully crafted using premium copper wire and an excellent design structure, significantly enhancing the electric field distribution. With thorough lighting
impulse analysis, its resistance to lightning impulses has been remarkably improved.
TANK
Our tank is meticulously constructed with high-quality steel. The surface undergoes a rust elimination process, phosphate coating treatment, and is painted with high-grade FVC anticorrosive paint. This ensures
superior resistance to corrosion from oil and chemical substances. Its aesthetically pleasing design makes it perfect for harsh outdoor environments, offering easy
installation and maintenance-free operation.
INSULATION OI L
The insulating oil used is PCB-free, inhibited, and generally conforms to IEC60296 standards.

Process Technology:
Core:
Our transformer's core is constructed from high-quality, cold rolled, grain-oriented silicon steel sheet with excellent magnetic permeability. Utilizing a full 45° slope lamination design, it effectively reduces no-load loss and no-load current.
By employing Simulating Analysis in the core model design, we precisely calculate vibration frequency and size, effectively preventing core cavity resonance.
The spring connections between the core & windings, and core & frame, ensure the noise level is 10 to 15dB lower than standard.
